Moments after the Giants sloshed the Patriots on Sunday night, thousands of New Yorkers jumped off the couch — and over to the loo.

According to Department of Environmental Protection, the city's water usage use spiked 13 percent across the Big Apple just minutes after Big Blue clenched the championship, the New York Post reported.

The flushing increase was so dramatic that the 30-foot-deep water level in the Hillview Reservoir in Yonkers fell by 2 inches.

“This was certainly a significant jump — especially for around 10 p.m. on Sunday night,” said Jim Roberts, deputy commissioner for the city’s DEP, to the Post. "It’s only going to happen on the Super Bowl."
